Tongkat ali, a medicinal herb together with the scientific name, Eurycoma longifolia Jack, is a popular herbal supplement with many different purported benefits. According to the British Journal of Sports Medicine, the active constituents of tongkat ali look like eurycomalacton, eurycomanon, and eurycomanol. Research studies in to the active chemical elements of Tongkat ali extract have revealed several possible uses for the herb, namely, being an aphrodisiac, ergogenic aid and cancer-fighting agent.
One of the purported uses of tongkat ali is as an ergogenic aid, or possibly a supplement that enhances the body’s adaptive response to exercise. Tongkat Ali is assumed to create this effect by causing a rise in the body’s levels of testosterone, a male se-x hormone which effects muscle size and gratification. According to a 2003 study by S. Hamzah as well as a. Yusof in “The British Journal of Sports Medicine,” a tongkat ali extract in conjunction with a weight-exercise program, caused an increase in lean body mass plus a loss in fat tissue relative to placebo. This supports using tongkat ali by athletes as being an ergogenic aid.
As tongkat ali is thought to enhance levels of the male se-x hormone testosterone, it may have utility like a libido-enhancer or general male se-xual aid. According to a 2003 study by Ang HH, Ngai TH and Tan TH in “The Journal of Phytomedicine,” when an extract of tongkat ali was administered to middle-aged rats their se-xual performance increased in accordance with the placebo group. The main effect observed had been a decrease in the hesitation-period of the rats, indicating a heightened libido.
Tongkat ali has been specifically studied as being a possible cancer-fighting agent, as a number of it’s chemical constituents have shown to exert anti-cancer effects in studies. As outlined by a 2005 study dexjpky63 Tee TT and Azimahtol HL in the journal, “Anticancer Research,” an extract of tongkat ali exerted anti-proliferative effects against human breast cancers cells. Inside a 2003 study conducted at National Cheng Kung University and published in “The Journal of Natural Products,” an extract of pine pollen tablet killed human cancer of the lung cells, in addition to demonstrating anti-malarial effects.
